Fold 1/2 cup black beans, 1 tablespoon salsa, and 1 slice cheddar cheese in a small flour tortilla. Cook in a dry nonstick pan until the cheese is melted and tortilla is lightly browned. Then wrap it in foil and stick in a plastic baggie for easy transport.
The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the cecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts â ascending, transverse, descending and sigmoid. These sections form an arch, which encircles the small intestine.
Despite its name, the small intestine is the largest part of the digestive tract. Even though the small intestine is only about one inch in diameter, the small intestine is approximately 20 to 23 feet long. Because the small intestine is long, the small intestine has a lot of surface area. This large surface area helps to ensure that the nutrients are absorbed. The small intestine has three parts called the duodenum, the jejuneum, and the ileum. As mentioned previously, the duodenum begins at the pyloric sphincter. It then wraps around the head of the pancreas and ends at a turn called the duodenojejuneal flexure. It then becomes the jejuneum.
